JOHN KARLE, OF BALTIMORE, MARYLAND.

ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 445,784, dated February 3, 1891.

Application filed September 13, 1890 Serial No. 3641905- (NO modell) T0 @ZZ 'whom it may concern.-

Be it known that I, JOHN KARLE, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Ash- Sifters, of which the following is a specification.

This invention relates to an ash-sitter; and its object is to provide means whereby the dust will be confined in the box and sieve.

In the accompanying drawings, illustrating my invention, Figure l is a top view of the ash-sitter. Fig. 2 is a top view of the slideway which. fits over the ash-box. Fig. 3 is a top view of the slide which carries the sieve. Fig. 4 is partly a side view and partly a longitudinal section of the ash-sitter. Fig. 5 shows partly an end View and partlya cross-section of the ash-sitter. Fig. 6 shows a top view of the ash receptacle and sieve.

The letter A designates the ash-box; B, the. lideway resting on the same; C, the slide or sievecarrier which travels in the said slideway; D, the removable receptacle and sieve for receiving the ashes and coals that are to be sifted. The slideway B rests on the ash-box A, and is provided with a central opening e, and has along either side edge a guide-wall f, which projects both above and below and extends the entire length of the slideway. The opening c in the bottom of the slideway is as long and as wide as theinside of the ash-box A. Two cross-strips h are fastened on the lower surface of the slideway B, and the space between them is equal to the outside length of the ash-box A. By this arrangement the slideway B when placed in position upon the ash-box A will not shift, but will remain secure in its position.

Resting upon the slideway B is a slide or sieve-carrier C, having runners or downwardly-projecting sides c, which slide upon the top surface of the slideway B and are guided bythe walls f. By this construction the body portion of the slide C is raised above the surface of the slideway B. This is done to prevent undue friction. The runners serve in lieu of rollers. The slide C just referred to has a centraly opening g, large enough to receive the sieve-case D. This opening g, however, is smaller than the opening e in the slideway B.

Two cross-strips b are fastened to the upper surface of theslideway B and at each end of the opening e. These cross-strips are made to close the space between the bottom of the slide C and the top of the slideway caused by the runners or downwardly-projecting sides c of the slide G, which rest upon the slideway. These cross-strips b prevent the ash-dust from escaping to the atmosphere through the said space between the slide C and slideway B.

The removable ash-screen or sievecase D consists of a rectangular case having two side walls h and two end walls t', a suitable woven screen or sievej, which forms the bottom, and a removable top E, which has on its under side strips or cleats 7e for holding the same in position when sifting. Each of the end walls t' of the ash-screen has an outside strip Zextending entirely across. These strips rest upon the slide C and support the ash-screen case when it occupies the central opening g of the slide. The supportingstrips Z on the sieve-case are placed some distance above the bottom edge n, so that the said edge n may depend or sit down below the top surface of the slideway B.. In this way the reciprocating movement ot' the slide C will be limited and controlled by the ends of the screen-case, which will strike against the edges 0 of the slideway-opening e.

A handle G, for imparting a reciprocating movement to the slide and ash-screen case, is fastened on the outside of one of the end walls t'. It willbe seen that this construction is simple and cheap, and all dust arising in the machine while sifting will be confined.-

I-Iaving described my invention, I claim-- In an ash-sifter, the combination of an ashbox A, a removable slideway B, resting on the ash-box and provided with an opening e,

l,f guide-walls f, projecting both above and below, and cross-strips h on the upper surface, a slide C to travel in said slideway, having a central opening smaller than the opening in said slideway and provided with runners c,

an ash-Screen ense D to ft in the opening iu In testimony whereof I ax my signature the said slide and having two outside supin 'che presence of two Witnesses. ports l/ on the walls of said screen to rest upon the slide C, a @over to close the said JOHN KARLE. 5 screen-'case and a handle by which motion \Vtnesses:

can be imparted to the slide, as and for the JNO. T. MADDOX,
